Crushed stone-sand mixture C7, (particle size 0-10 mm.)

Purpose: it is used for arrangement of bases and additional layers of bases of motorways and aerodromes bases, reinforcement of roadsides of motorways:
Design features:
- Grain composition;
- Content of grains of lamellar (flatter) and needle-shaped;
- Dusty and clay content;
- Clay content in lumps;
- Crushed stone strength (crushability) grade;
- Bulk density;
- Mark on water resistance of crushed stone;
- Mark on plasticity;
- Mark on frost resistance of crushed stone;
- Specific efficiency of natural radionuclides activity of crushed stone;
- Structure stability against decay;
Advantages:
1. Wide range of products;
2. The percentage of content of grains of lamellar and needle shape does not exceed 13%, therefore the use of this crushed stone improves the quality of concrete structures and asphalt concrete pavements;
3. The coefficient of bulk density of dolomite crushed stone is lower than that of granite crushed stone, therefore, with comparable strength and other characteristics of ra...
